The Molex 430450427 is a 4-circuit, dual-row vertical header from the Micro-Fit 3.0 43045 series. Typical applications include automotive, industrial, medical, and telecommunications equipment where a reliable, vibration-resistant power connection is needed.
The 600 V rating is high for a 3.00 mm pitch connector, giving substantial creepage margin for industrial and automotive environments. The 4-wall shrouding and locking ramp protect the pins from damage and resist vibration-induced disconnection.
This vertical through-hole header mates with the matching Micro-Fit 3.0 receptacle housing (sold separately), which accepts the crimp terminals for 20-24 AWG wire. The locking ramp provides an audible click when fully seated. The 0.125" (3.18 mm) solder post length is designed for standard PCB thicknesses. The board guide feature aids alignment during assembly.
